2. Description of the Related Art In this type of work, particularly in a mounting board, in order to protect mounted components, they are stored and protected in a predetermined tray, a cardboard box or a storage frame for storage or transportation. Of these, when the number of workpieces to be stored is large, a cardboard box or a storage frame is often used in terms of transportation efficiency. The box made of corrugated cardboard has a partition formed inside or a film with a groove formed is attached to the inside of the box. In addition, the storage frame is provided with two upright side plates facing each other between a top plate and a bottom plate, which are provided at regular intervals so as to cope with changes in the width dimension of the work, and one of the side plates is fixed. A side plate is often used, and the other side is a movable side plate that can move in parallel with the fixed side plate and can be fixed at a desired position.

[0003]

The former has a problem that it is difficult to obtain the dimensional accuracy, so that it is difficult to automatically store and take out the robot using a robot. Further, the latter has a problem that the storage efficiency is lower than the volume of the storage frame when the width of the work is small, such as a divided printed circuit board. The present invention has been made to solve the above-mentioned problems, and automatic storage using a robot,
An object of the present invention is to provide a work storage device that is suitable for taking out and has better storage efficiency than when a storage frame with a variable storage width is used alone.

[0004]

In order to achieve the object, the present invention adopts the following structure, that is, a work storage tray configured to store a plurality of works, and the tray. And a storage frame configured to store and store in multiple stages.

Further, the tray comprises a tray plate and a work holder formed separately from the tray plate, and a step portion is formed on an upper portion of the work holder so that the work is stepped by a plurality of work holders. It is desirable that the work holder is fixed to the tray plate so that it can be accommodated between the parts.

Further, the storage frame is provided with two upright side plates facing each other between a top plate and a bottom plate, which are provided at a constant interval, and one of the side plates is a fixed side plate and the other is the fixed side plate. It is desirable that the movable side plate be movable in parallel with the side plate and fixed at a desired position.

Further, a tray guide for receiving the tray, an elevator conveyor for moving the storage frame up and down according to a tray storage pitch of the storage frame, a pusher for pushing the tray out of the storage frame onto the tray guide, It is desirable to provide a pusher for pushing the tray containing the work into the storage frame from above the tray guide.

[0008]

According to the present invention, since a plurality of works can be stored in the tray, if the works are stored in the tray and then the tray is stored in the storage frame, the width of the work is small. Even in this case, it is possible to reduce the wasted space of the storage frame. Further, if the tray is formed by mechanical processing such as punching or cutting, dimensional accuracy can be obtained, and there is no fear of hindering automatic storage and removal by using a robot.
